Watch Fred Armisen and J Mascis Cover TLC’s “Waterfalls”

Having formed a steady working relationship over the last year, Portlandia’s Fred Armisen and Dinosaur Jr. frontman J Mascis teamed up again last Friday for a performance at Boston’s Berklee School of Music.

Armisen and Mascis were also joined by Leigh Nash (Sixpence None The Richer) for a cover of TLC’s breakout hit “Waterfalls.” Mascis, cool as ever, wails in the background while Armisen provides the comedy for the seven-minute rendition of the song.

In recent months, Mascis and Armisen have teamed up on several projects, with Mascis making a guest appearance on Portlandia and performing on Armisen’s farewell sketch as Ian Rubbish on SNL.
